Pa tented Dec.'13, 193s Johnson sioiaiins. ntion' relates to sclfosures' for ,reoe'p'ta- 1 ing: acover with a extending over thisfout- Such cove ave; heretofore been secured by contracting a'fringiof channel form over thetjlip" and/under the out turned edgei The presentinvention is directed to: an'improve'ment of the Flocking' meansv for securing the cover. In'some "of )the prior structures a: single lever mechanism is'used foi 'efl'ecting the" locking of the; locking ring. In the-presentiriventiona double lever ,mechanism is used for'actuating the" ring. A

I complete operationof the 'ring requires considerable pressure. The double lever gives a'- great er total'movement than 'is practicalkwith a single lever {and consequently greater L power in- Y seating v [the ring. It makes'pessibIe also a short lever:

This simplifiesthe mechanis'm, makes it more readily housedin the depression of 1 the cover; f more surely locked in plac'e' and strengthens the mechanism as av whole; thus permI-tting of lighter construction. i lt also leaves a greaterpart of the zs cove'r exposed for printing. Features and details" ofthe invention will appear from thespeciflcatlon 1.Fig. t lishows a: p1an view of":v a fragmented: the

to the ring. These plates extend inwardly from the ring and are prefe'rably slightly depressed on their inner'ends' 9 'so asto be within the depression formed- 1h the'cover. Levers- IO- are pivotally secured by pins" II' on" the plates 8, the levers being preferably arranged on the under sides of the plates. The levers arealso pivotally secured toa connecting bar 1'2 by pivot pins l3. The outer ends maof the levers are'fo'rmed to permit the insertion of the fingers for readily operating the levers. By swinging the levers toward the partiof'thefring"adjacentto its supporting plate the ends'of the'ring' are drawn together and the ring thus contracted; As the levers approach the, ring, a'sshowninFig. 1', the pivots I3 are carriedi'n'to', or slightly beyond, alinement so that the expansion pressure of the ring tends to hold the; levers'i'n their locked" position.

Iiior'dtr to'nioresecurely lock the levers the .connecting barfZ is'ext'ended'beyond the pivot i3 and. the locking" shoulders, or catches M are formed ori the" edgeof the bar and as the levers approach" their closed'position they are deflected, or, spruiigupwar'd' sufficiently to'pass the shoulders; As'the leve'rs' reach their final, or closing position and'are released they spring back to the connecting barn, back of the catches I4 and'are thiis securely held in locked position and adjacent'tothe ring. The levers are of suflicient resiliencfto'per'mit-their" springing over the shoul dersf i' engagement and disengagement.

In the structure shown it will beseen thatthe contracting movement oi. the ends involves the sum of the leveraction ofthe two levers and consequently the lever arm of each lever controlling the movementmay;becomparatively short and in consequence; the power end of the lever may also be comparatively short. The connecting bar afiordsa simplification of the connection of the lever mechanism and also affords a very simple means for supporting the locking shoulders. It is preferable to place the levers under the supporting'plates so that they may be more completely protected and the levers carried into the depres sion of the cover. While I have shown the levers thus connected the invention in its broader phases is not limited to a connection involving the interposed connecting bar.

Preferably the levers are so alined that when sprung to cross each other in the open position [of the mechanism, the friction between the two will maintain the open position for ease in placing the ring over the head of the barrel. This is particularly useful for holding the ring open so invention as operating on a locking ring arranged outside of the receptacle, in the broader aspects. of the invention and some features thereof it may be possible to arrange the locking ring in a different relation to the receptacle in this respect.

What I claim as new is: I 1. In a device of the character described, the combination of a receptacle having 'an outturned edge; a cover having a seating edgeien gaging the out-turned edge; a contractible split closing ring of channel fOrm'incrossI section ex.-

tending over the periphery of the cover and under the out-turned edge; a lever pivotally secured to each end of the ring the pivots of said levers being substantially parallel to the axis of V the ring; and means connecting the levers, said levers being directed to exert a closing pressure the ring.

2. In a device of the character described,the

on the ring with a movement of the levers toward combination of a receptacle having an outturned edge; a cover having its edge seating on the out-turned edge; a contractible split closing ring of channel form in cross section; said ring having an inwardly extending lever supporting plate at each end; a lever pivotally secured tov each plate and within the ring; and means connecting the levers, said levers being directed to exert a closing pressure on the ring with'a movement of the levers toward the ring. f

3. In a device of the character described, the combination of a rectangle having an outturned edge; a coverhaving its edge seating on the out-turned edge; a contractible split closing" ring of channel form in cross section, said'ring having an inwardly extending lever supportingj plate at each end; a lever pivotally secured to the underside of each plate and within the'ring;

and means connecting the levers, said levers being directed to exert a closing pressure on the ring with a movement of the levers toward the ring.

4. In a device of the: character described, the combination of a receptacle havingfan out turned edge; a cover having a seating edge" en gaging the out-turned edge; a contractible split closing ring of channel form in cross section extending over the periphery of the cover and under'the out-turned edge; a lever pivotally secured to each end of the ring; means connecting the levers, said levers being directed to exert closing pressure on the ring with a-movement of the levers toward the ring; and shoulders on the connecting means adapted to engage the levers and lock them in closed position.
